I'd say xpadder as well. But you might not need it.. The keys are rebindable so you might be able to map it with the controller... I don't have an oculus and i like keyboard and mouse so i've never tried it myself, but as long as you have the proper wire and driver installed on windows it should work.... unless your on windows 10. Than your probably fucked since nothing works with windows 10.
Not true. If it was made for Windows 8, it should work in Windows 10. Where people run into trouble is with stuff that worked in Windows 8 but was made for Windows XP. Maybe they should take that as a hint that it's time to upgrade, since clearly the manufacturer gave it up years ago.
